—Link scheduling is a fundamental design issue in multihop wireless networks. All existing link scheduling algorithms require the precise information of the positions, and/or communication/interference radii of all nodes. For practical networks, it is not only difficult or expensive to obtain these parameters, but also often impossible to get their precise(More)
This paper addresses the join selection and power assignment of a largest set of given links which can communicate successfully at the same time under the physical interference model in the simplex mode. For the special setting in which all nodes have unlimited maximum transmission power, Kesselheim [8] developed an constant approximation algorithm. For the(More)
We study the <i>multicast capacity</i> of a random wireless network consisting of <i>n</i> randomly placed <i>ordinary wireless nodes</i> and <i>m</i> regularly placed <i>base stations</i> in a square region, known as a <i>hybrid network</i>. All ordinary wireless nodes have the uniform transmission range <i>r</i> and uniform interference range(More)
Multiple-input multiple-output (MIMO) technology provides a means of boosting network capacity without requiring additional spectrum. It has received widespread attention over the past decade from both industry and academic researchers, now forming a key component of nearly all emerging wireless standards. Despite the huge promise and considerable(More)
—Maximizing the wireless network capacity under physical interference model is notoriously hard due to the non-locality and the additive nature of the wireless interference under the physical interference model. This problem has been extensively studied recently with the achievable approximation bounds progressively improved from the linear factor to(More)
—Multiflow problems are one of the most fundamental problems in both wired networks and wireless networks. Due to the cross-layer nature, multiflow problems in wireless networks are significantly harder than their counterparts in wired networks and have received much research interest over the past decade. Common to most other early-staged research, the(More)
